Oracle 11g DataGuard 物理备库配置及Active DataGuard测试

说明:
本文安装配置了Oracle 11g Dataguard 物理备库,并测试了11g Dataguard 物理备库新特性Active Data Guard, 是Oracle Database Enterprise Edition的一个功能,需要额外授权,本文只用于测试。

一、环境介绍
1. 主数据库环境
操作系统版本: OEL5.8 x64
数据库版本  : Oracle 11.2.0.3 x64
数据库sid名 : orcl

2. 备库环境
操作系统版本: OEL5.8 x64
数据库版本  : Oracle 11.2.0.3 x64 (只安装oracle数据库软件,no netca dbca)
数据库sid名 : orcl

3. DataGuard启动顺序
启动顺序:先启备库,后启主库
关闭顺序:先关主库,后关备库

二、主数据库配置
1. 配置hosts文件
# vi /etc/hosts
192.168.233.200  rman
192.168.233.150  slave

2. 修改配置lisener监听文件
$ cat /u01/app/oracle/product/11.2.0/db_1/network/admin/listener.ora 
LISTENER =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.233.200)(PORT = 1521))
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
    )
  )
SID_LIST_LISTENER =
  (SID_LIST =
    (SID_DESC =
      (GLOBAL_DBNAME = orcl)
      (ORACLE_HOME = /u01/app/oracle/product/11.2.0/db_1)
      (SID_NAME = orcl)
    )
  )

3. 修改配置tnsname.ora文件
说明:ORCL是主库的服务名,DG是备库的服务名。
$ vi /u01/app/oracle/product/11.2.0/db_1/network/admin/tnsnames.ora
ORCL =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.233.200)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = orcl)
    )
  )
DG =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.233.150)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = abc)
    )
  )

4. 修改配置成规档模式
1)、检查数据库是否处于归档状态
SQL> archive log list;
SQL> shutdown immediate;
SQL> startup mount;
SQL> alter database archivelog;
SQL> alter database open;

2)、将主库设置为 FORCE LOGGING 模式
SQL> alter database force logging;
SQL> select force_logging from v$database;
FORCE_LOG
———
YES

5. 修改参数文件
SQL>
alter system set db_unique_name='ORCL' scope=spfile; 
alter system set log_archive_config='DG_CONFIG=(ORCL,DG)'; 
alter system set log_archive_dest_1='LOCATION=/u01/archivelog/ valid_for=(all_logfiles,all_roles)
db_unique_name=ORCL' scope=spfile;
alter system set log_archive_dest_2='SERVICE=DG lgwr async valid_for=(online_logfile,primary_role)
db_unique_name=DG'; 
alter system set fal_client='ORCL'; 
alter system set fal_server='DG'; 
alter system set standby_file_management=auto; 
alter database add standby logfile group 4 '/u01/app/oracle/oradata/orcl/standby_redo04.log' size 50M; alter database add standby logfile group 5 '/u01/app/oracle/oradata/orcl/standby_redo05.log' size 50M;
alter database add standby logfile group 6 '/u01/app/oracle/oradata/orcl/standby_redo06.log' size 50M; alter database add standby logfile group 7 '/u01/app/oracle/oradata/orcl/standby_redo07.log' size 50M;
 
shutdown immediate 
startup 
create pfile from spfile; 

6. 将pfile文件拷贝到备库。
$ scp /u01/app/oracle/product/11.2.0/db_1/dbs/initorcl.ora 192.168.233.150:/home/oracle/
